Blue Color Synthetic Sapphire Pendant Necklace With Round Shape

Introduction

Sapphire, which is derived from the Latin Spphins, which means blue; it belongs to the corundum group of minerals in the trigonal crystal system. In the gem world, all colors of gem-grade corundum other than rubies are called sapphires.

The main component of sapphire is alumina (Al2O3). Corundum contains trace elements such as iron (Fe) and titanium (Ti), and presents colors such as blue, sky blue, and light blue, among which the bright sky blue is the best.

Sapphire crystal (Sapphire) is a synthetic material that combines the advantages of plastic glass and mineral glass. It has a high density and a hardness of 9 degrees, second only to diamond hardness of 10 degrees. It is not easy to scratch and has high transparency. Characteristic, even in the case of impact, the glass will only produce cracks, and will not fall off the whole piece. The sapphire glass table mirror is resistant to wear and scratches. However, the disadvantage of sapphire is that it is fragile due to its advantages. Therefore, improper operations such as bumps, heavy pressures, and heavy drops are not suitable for use.

Basic characteristics

These excellent optical, mechanical, thermal, chemical and electrical properties determine its important position and role in the military and civilian fields.

Synthesis experiments with rubies and sapphires began in the 1860s, but it was not until the early 20th century, when the Werner Leaf Furnace was born, that synthetic rubies were successful. Synthetic sapphire is crystallized from the melt, its main components are Al2O3, in the synthesis of the addition of trace amounts of Cr, then red, that is, synthetic ruby; If you add a trace amount of Ti, you become a synthetic sapphire.

Synthetic rubies and sapphires are very similar in appearance and nature to natural sapphires, so it is difficult to distinguish them. Now mainly according to the sample internal package differences for identification, such as synthetic ruby often contains bubbles, fine arc lines and so on. If the package is small, these phenomena may not be observed with a magnifying glass, and an optical microscope is needed to observe the energy-picking resolution.

The cutting of colorful gems is different from that of diamonds. Because of the wide variety and different crystal structure, different cutting methods are needed to show the gloss and color of gems, and to take care of the maximum, so there are various cutting methods.

Oval cutting is the most common way of cutting gemstones. The gems cut by the oval cutting method, viewed from above, have soft lines and can compete with diamonds in gloss, and have a strong fire color.

The best number of facets for round diamond cutting is 57 or 58, which is also the most ideal diamond cutting method. Now it is widely used, and many colored gems also use this type of cutting method. The round diamond-shaped cut makes the gem show the most shining fire color, so that the fire color is concentrated on the gem, which is particularly eye-catching.

The pear-shaped cut gem is like a crystal teardrop, giving people a beautiful and romantic feeling. Aquamarine, Morgan and other small fresh gems are more suitable for pear-shaped cutting. Like Aquamarine, it looks like a blue tear after being cut and is very popular with young girls.

Triangular cutting is used for gemstone pendants. The characteristic is that the apex and bottom of the cut gemstone are prominent, allowing everyone to see the natural luster of the gemstone, and the fire color will be better. Therefore, many gems are cut in triangles, such as aquamarine and morganite.
